Ar 15 Trigger Won’t Pull: A Comprehensive Guide
Are you facing the frustrating issue of your AR-15 trigger not pulling? Don’t worry; you’re not alone. This problem can occur due to various reasons, and understanding them can help you fix the issue effectively. In this article, we will delve into the possible causes, symptoms, and solutions for an AR-15 trigger that won’t pull. Let’s get started.
Understanding the AR-15 Trigger Mechanism
The AR-15 trigger mechanism is a complex assembly that includes the trigger, hammer, sear, and disconnect. When you pull the trigger, it releases the hammer, which in turn strikes the primer of the cartridge, causing the firearm to fire. If any of these components are not functioning correctly, the trigger may fail to pull.
Common Causes of an AR-15 Trigger That Won’t Pull
Here are some of the most common reasons why your AR-15 trigger might not pull:
| Issue | Causes |
|---|---|
| Trigger Stuck | Debris, corrosion, or a worn-out trigger assembly |
| Hammer Not Seating Properly | Worn-out hammer or sear, or a misaligned hammer pin |
| Trigger Pull Too Heavy | Worn-out sear or trigger spring |
| Trigger Not Engaging | Malfunctioning disconnect, worn-out sear, or a misaligned hammer pin |
Diagnosing the Problem
Before attempting to fix the issue, it’s essential to diagnose the problem correctly. Here are some steps you can follow:
- Check for any visible debris or corrosion in the trigger assembly.
- Inspect the hammer and sear for wear or damage.
- Ensure that the hammer pin is properly seated and not loose.
- Test the trigger pull weight using a trigger pull gauge.
Solutions for an AR-15 Trigger That Won’t Pull
Once you’ve diagnosed the problem, you can proceed with the following solutions:
- Trigger Stuck: Clean the trigger assembly thoroughly, using a cleaning solvent and a cotton swab. If necessary, replace the worn-out trigger assembly.
- Hammer Not Seating Properly: Check the hammer and sear for wear or damage. If they are worn out, replace them. Ensure that the hammer pin is properly seated and not loose.
- Trigger Pull Too Heavy: Replace the worn-out sear or trigger spring. You can also adjust the trigger pull weight by replacing the trigger spring with a heavier or lighter one.
- Trigger Not Engaging: Check the disconnect for any damage or misalignment. If necessary, replace the disconnect. Ensure that the hammer pin is properly seated and not loose.
